Re: QLG1 Arduino

@Don Degregori  I now see what you mean re the use of "fix" and how it affects the data being printed, but that is not the core issue.

The gentleman's code is basically a clone/copy of one of the adafruit library examples. 

If you remove the "fix" boolean test, and just have it print data, there is still..no data. I see this issue on both the QLG-1 and the other module I have.

For whatever reason, which i'm now admittedly obsessed to figure out, it appears his approach does work with the adafruit module, but not the two I have. And as I sense Hans feels, and as it seems to me, that just doesn't make sense. There are some nmea data flag tests that he removed that is in the adafruit example, and that's where my guess the issue is.

Back to digging..

 

Re: #qcx QCX Firmware 1.01 released #qcx

Hello, everyone.

I just tried updating my QCX with the 1.01a hex file using Arduino and avrdudess (2.10). I am very inexperienced with this process.  I tried following the nice tutorial by Simon VK3ELH and everything seemed to work fine during the writing and reading process.  A screen capture from avrdudess is shown below.  I highlighted in yellow what I might have done wrong. 
Anyway, after the update the screen on the QCX simply says "Use original IC!" and the radio is nonfunctional.  I'm sure I did something stupid.  Is there any recourse other than to order a new firmware chip?

Many thanks,
Tom N9GVP

 

630m WSPR with Ultimate 3S + G0MRF amp

John AE5X
 

I spent three hours and about 5 inches (7.5 cm) of solder yesterday building two small kits: Hans' LP filter for the 630m band (for the U3S) and David G0MRF's 5-watt amp kit. I'm happy to report that the two play well together although I'm only radiating into a dummy load for the moment. That will change this weekend when me, my helpful neighbor* and the drone will install the seasonal antenna into yon tall pines.

If you have a U3S and a penchant to explore life below the AM broadcast band, I think this makes for a winning combo. Details and photos are here:

Re: QLG1 Arduino

The issue is *not* the adafruit libraries, its the supporting code itself.

I went back and tried a few of the examples provided within the Adafruit library package, and they worked fine, including one serializing and printing the data.

@Don Degreogri: I need to spend some time with the guy's code to see if I can figure out why it doesn't work with my two boards (but does with his), but there are plenty of other usable options both within the TinyGPS library, and the Adafruit library.

There should be an attached image, it is a Sparkfun AVR Programmer. I
have successfully used it to program a couple of QRP Labs devices as
well as a few other odds and ends.

avrdude recognizes it as a usbtiny.

Will it work for everything you want to use it for? I don't know but it
has worked for my simple needs.

I don't remember what I paid for it but I am a cheap whatever so it
probably wasn't much.

Re: Enamel coating

Graham, VE3GTC
 

it is interesting that this topic came up again as I have been doing some tests of my own.

First off, not all magnetic has "enamel" insulation. In quotes because enamel can have different meanings to different people.

There are many different insulation materials that are used on magnet wire. The commonly available solderable type of magnet wire uses a urethane insulation and may be nema MW-80 compatible. This is a very broad topic and cannot be summed up in 100 words or less.

I did some tests on some nema mw-80 single coated 155 degC magnet wire. This is urethane coated and is of the solderable type.

to sum it up:

Acetone did work but took more than an hour to soften the insulation enough that it could be wiped off with a paper towel.

New non methylene chloride based paint stripper also worked but required a 15 minute soak to soften sufficiently that it could wiped off with a paper towel.

methylene chloride based paint stripper did the trick but took a one a half minute soak to accomplish the task.

Methylene chloride based paint strippers are not that common. You will not find them at home depot or lowes or walmart not because they are banned by the EPA but because of a letter writing campaign by a few concerned groups.  You can still find it in some small specialty paint stores or independent hardware stores. Apparently after Nov 22, 2019 there will be further restrictions on availability but it will not be banned at least I can not find definitive information to that detail.

This chemical requires care in it's use but it is not really any more dangerous than many other solvents when used with proper care. It has an interesting history. 

The story goes that in the 40's this chemical was introduced as an alternative to using the high flammable solvents then in use. 


Read the lables, use with due care with proper ventilation and do not use in a bath tub or other confined areas.

cheers, Graham ve3gtc

Re: How do I get the ultimate 3S and low pass filter boards to change bands ?

Roger Hill
 

Hi Paul:

So when you go through setup, do you see each of the 6 slots with different frequencies? It sound to me like you have repeatedly programmed slot zero, so it is just picking up the last one. Remember too that you have to set the 'max number of slots' parameter...I forget what it is called, but it is in the manual (my U3S is 4000 miles away!).

I thought I set it for the WSPR frequency on all six bands, (0-5) but only transmits on the last band that I programmed.
I just can’t find it in the instructions.
I am hoping this is easy because I have a six band vertical and I would like to run it from 80 through 10 meters.

Re: Show off your enclosure

Jim W8JD
 

Here is mine in an old Netgear router case, not very pretty but functional.  There are four 18650 lithium batteries inside with a charging board which is working out well.  The batteries are 2500 mah so it runs a long time.  I found knobs that were long enough so I did not have to remote the gain and tune which saved space and work.

Hi Geoff
Ah, those are just there if I want to use it as a bench PSU for some other project. As you might expect, the same breaks out on the back of the unit and connects to the QCX with a small patch lead.

I used Atmel Studio 7 on W10, and an AVR Dragon to flash the MCU with v1.01

Worked fine.

Didn't have to change the fuses.

There might be simpler ways of doing this.
